Nuflbf, filed Juli' 1li, i906. Yin lisis coniiwior Lhe Sides of Lilo channel rnijriceni in the end :are given an @edward flaite or inclination as shown ai: 12E. A The filling blocks 13 and 14 nre arranged :so to incluse the por Lion 0i the; tension member wiliin the Channel, and aise have flaring portions which will lie along Lire flaring portions 10 of the clniniiei. When heated and welded Lowther the ond of the beam wil have the shape shown in Fig. 1U. i y A While any suitable ferm or construction o strut member may be employed in connection with my improved beam, the form shown in Figs. iii to 19 inclusive is preferred. This lorm consists of a head portion 15 integral with the legs or supporting members 16 and provided with a seat for the compression member. When form ing this strut member the head is first shaped with the legs parallel with each other und with the axis of the seat in tlie head for the tension member. The legs are then twisted so as to throw the sides of the legs between which the brake lever is arranged, at the desired angle. This twisting will throw the lower portions or feet 17 of the strut out on each side of a compression member und in order to bring them back into position on the coxnpression member, :in edgewise bend is made as indiciited at e, thereby bringing the feet 17 into proper po- /1 sition on the compression member to whieh they are securedin any suitable manner as by bolts or rivets. It is preferredl inox-der to hold the legs in proper relative position that :i spacing block 18 should be arr-.urged between the legs as shown, said block being held in position by a bolt or rivet. As shown in Figs. 17 and 18 an ear bolt 25 to which the beam supporting chain may be attached is passed through the strut and secured in porsition by riveting, or in any suitable manner.

111 order to prevent an unequal wear of the brake-shoe due to its Changes of position relative to the wheel when the car is loaded or unloaded, it is preferred that the brake beam head should he adjuslnbly mounted on the beam. To this end the end of my improved beson is rounded on one sido, its shown in Figs. 11 und 133, thus forming a, sent lo for thiheud 19 which is provided with eyes or sockets 2i) for the'reeeption o the end of ilifbeam. This seat portion ol the beam is not a roml plete cylinder' as will be sven by roi'ereneeto Fig. li, `ind in order to leek the bend on the lit-:Lin l providt` it lor-king block 21 fitting within the sockel und h-.iving logs or shoulders 22 enguging thil outside walls ot' the socket.r This locking piece 21 muy be ki-uri-d to o r formed integrati with n spring 2L. lirmly speurt-d to the ompression member :is shown in Figs. il, 12 :ind 14. When it is desired to plaee :i head on the boum, the locking block is [oi-eed toward the sent, the heini slipped into position und the spring rele-used. The loi'liint1 block will their lr-.iw thi-` lieud lirmly to ils sont und will bold the some os against movenu-nt alongy the beam. il. hilo permitting the :intein-nti(- shifling oi the hind the .spring lock will hohl the some lirmly not only ns against. di-plznennnt olong its sont but. nlso :is ogninsi. rnttliin; or other undesired movement. 'lhis nmnner of sol-m2 ini; the hood on linA Iii-:im avoids the use ot' rivets und bolts und permits thiI houd being easily und quil-kly romovld i-von when |||tA broke bottin is ol' Ih(` insidtA hungr type.

ln order to prevent the houd l'rom movingr uround on its seul., thereby musing oneor lhrolhorond from rubbingon thi,- vt'hoel, hondV is provided with V.slr.i|n-d teeth engaging willi simil-.ir tooth on ils` sont. 'lhis t-onstruction will permit llo* `i- `d being autonmtir'zllly shifted when the brakes ore applied, but will previ-nt rotary movement nt other times. .A

In order to prevent the head [rom becoming unloirked in ense of the breaking oi' the spring, :i key 24 may be inserted between 'ihe looking bleek und the end of the beam, said key boing held in position by u. bolt or other suitable means. 111 Fig. 14 the slipping of the houd oli of the beam in ense oi a breaking of a. spring 23, is prevented by a stop 24 consisting of a bolt screwing into the beam.

As shown in Fig. l5 my improved int-:ins for lookingjy the head in position muy be applied to construction in which an uutonunie adjustment ol the hind is not desired. i As shown the sent on the head and the socket ill the head may be made angular in eross section und the lie-ad looked in any other stiitnble manner I claim herein as my invention:
